That is the billing given by former Munster and Cardiff outside-half Paul Burke to the personal duel battle between opposing fly-halves Ronan O'Gara and Nicky Robinson in Sunday's Heineken Cup showdown.

The duo have had contrasting fortunes coming into the European encounter which the Blues must win if they are to keep their slim quarter-final qualifications hopes alive.

The 66-times capped O'Gara is the form outside-half in Europe after his superb autumn series in a winning Irish side, while Robinson was omitted from the Welsh squad for the international series.

And Burke, 33, is the perfect person to judge who will prevail in the battle of the number 10s - a contest which will go a long way to deciding the victors at the Arms Park on Sunday.

The former Irish outside-half was a team-mate of O'Gara at Munster and watched Robinson come through the Arms Park ranks before leaving Cardiff in 2001.

'It will be like the old master v the young pretender,' said the 33-year-old, who won 13 caps for Ireland between 1995 and 2003.

'It will be an intriguing duel between Nicky and Ronan.

'Nicky is a fantastic footballer who has great distribution and a sweet left foot.

'He is getting better all the time and the next stage is consistently learning how to control a game.

'Ronan is a player who is in the prime of his career and has developed into the complete outside-half.

'He has always been seen as a player who can control a game by sitting in the pocket and keep his side going forward by kicking the ball in the corners.

'But what he will say, and what you have seen especially in the autumn, is he can also be an effective attacker.

'Ronan has excellent distribution and he has shown he can release his backs and challenge defences.'

Burke, now with the Leicester Tigers, has already suffered at the hands of his former provincial team-mate and Irish rival this season.

O'Gara kicked a last-gasp 50-metre penalty to defeat the Tigers in the Heineken Cup pool game at their Welford Road lair in an European encounter where Burke admitted he was guilty of a poor kicking performance.

'When Leicester lost to Munster they capitalised on our errors,' said O'Gara.

'I missed a couple of kicks and we spilled some ball and they punished us. The Blues can definitely win at home against Munster but they will have to eliminate the mistakes.'

And while O'Gara is regarded as the driving force behind the Munster side who won the Heineken Cup last season, Burke believes the Blues can expose him if they target the Lions fly-half early on.

'Ronan is the talisman for Munster and he makes them tick,' said Burke. 'The Munster ship is always sailing smooth when he is on form.

'But if you can rough him up then the Munster path can be driven off course. That is what the Blues have to do early on.'

And Burke had words of encouragement for the Blues ahead of their make-or-break European tie.

'Dai Young and Rob Howley are building a side who are capable of competing with the best in Europe,' said Burke.
